OF BLOOMINGTON, ILLINOIS,

ASSIGNOR TO PORTABLE ELEVATOR MFG. OO., A CORPORATION OF ILLINOIS.

WAGON-DUMP.

Application filed June 18,

To all whom it may concern:

le it known that I, lloi-IN FWIHTE, a citizen of the United States, residing at Bloomington, in the count-y of McLean and State of Illinois,` have invented certain new and useful Improvements in Wagon-Dumps, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in wagon dumps or jacks designed to elevate the forward end of a wagon to discharge the load contained therein into a drag' or feeder and more particularly to that type of jack disclosed in my co-pending application filed Feb. l2, i906, Serial No. 300,828, and known as straddle jacks, in which the jack and the elevating mechanism therefor are fashioned to rest between the wheels of the wagon to be dumped.

The object of the present invention is the provision of improved means for effecting the raising and lowering of the jack.

A further object of the invention is the provision of means whereby a jack of this character may be readily adapted for use with wagons of varying lengths.

Other objects of the invention will be from the detailed description hereinafter when read in connection with the accompanying drawing forming a part hereof, wherein a preferable embodiment of my invention is shown and wherein like numerals of reference refer to similar parts in the several views.

In the drawings: Figure l is a side elevation of my improved jack. Fig. 2 is a perspective view of the forward end of the jack. Fig. 3 is a perspective View of the rear end of the jack showing the drag in its lowered position. Fig. 4 is a detail view showing the sectional rack in its housed position. Fig. 5 is a per- Fig. 6 is a top plan view of the same, and Fig. 7 is a detail view of one of the links of the sectional rack. Figs. 8 and 9 are detail views showing modified forms of stop blocks for engaging the wagon axle. i

Referring now more particularly to the drawings, A A designate a pair of longitudinally spaced supporting beams, which are supported upon and secured in any suitable manner to cross pieces which are adapted to rest upon the ground.

Secured te the supporting beams A A is the jack B, which is similar in construction to the jack disclosed in my pending application hereinbefore referred to, consisting' of a pair of beams b b, the lower ends of which extend between the spaced supporting beams A A adjacent one end thereof and are connected thereto by a suitable pivot bolt passing therethrough. As in my former application', the upper surfaces of the beams b b forming the jack B are slightly beveled at their Speeieation of Letters Patent.

outer ends to form a seat for the forward `axle of the wagon to be dumped.

C C designate a pair of links, the lower ends of which are pivotally secured to the forward ends of the supporting beams A A, by a suitable pivot bolt passing therethrough and the upper ends of which are pivotally connected in any suitable manner to the lower ends of a pair of links D, the upper ends of which are pivotally secured to the forward ends of the jack beam b b by means of a suitable pivot bolt d passing therethrough. The upper ends of the links D project above the upper surfaces of the jack beams b b when the same are elevated and constitute a stop to prevent the axle of the wagon supported thereon from slipping downwardly along the upper surface of the jack as the same is elevated.

E E designate a pair of links similar in construction to the links D D, the upper ends of which are pivotally secured to the jack beam in rear of the links D D and the lower ends of which are pivotally connected to the links O C below their connection with the links D D. The lower ends of the links E E are provided with elongated slots therein e at the point of their connection with the links O C, in order to permit the slight longitudinal movement which will be imparted to said links when the jack is raised and lowered. The upper ends of the links E E extend above the upper surfaces of the jack beam when the jack is raised and lowered and the purpose of employing said links is to provide means whereby wagons of different lengths may be dumped without the necessity of adjusting the jack so that when the wagon is elevated its rear end will be properly positioned to discharge the load contained therein into the drag or feeder.l Instead of providing the jack with the several setsy of links for engaging the forward axles of wagons of different lengths, the same purpose may be subserved by providing the forward ends of the jack beams with a plurality of stop blocks bf or with stop blocks b2 which may be adjusted longitudinally of the jack beams.

Journaled between suitable bearing blocks secured to the upper surfaces of the rear ends of the supporting beams A A is a drive shaft F, one end of which projects rearwardly beyond the bearing block and has secured thereto a collar f provided with aclutch face of any suitable construction.

Loosely mounted on the shaft F are a gear wheelF and a sprocket wheel F2 and keyed upon said shaft between said gear and sprocket wheels is a clutch member F3 which may be moved longitudinally to cause either the gear wheel or the sprocket wheel to rotate with the shaft.

G designates a shaft which is journaled in suitable bearings below the shaft F between the supporting beams A A and which extends substantially the entire length of said supporting beams, the forward end thereof being journaled in a suitable bearing secured to the inner 5 side of the forward end of one of said supporting beams.

Secured to the shaft G is a gear wheel G which meshes with the gear wheel F secured upon the shaft F and a sprocket wheel G2, which is connected by a suitable chain with the sprocket wheel F2 upon the shaft F, From this construction it will ae apparent 4that by shifting the clutch member F3 to cause either the gear wheel F or the sprocket wheel F2 to rotate with the shaft F, the direction of rotation of the shaft G can be governed. The clutch member F3 is shifted by means of an arm H which is pivotally secured to one side of a beam l which is secured to the under sides of the bearing blocks for the shaft F and projects rearwardly therefrom to form a support for the 'forward end of the drag when the same is in its lowered position.

Pivotally secured to the arm H is a stud 71y which is provided with a recess therein adapted to loosely receive an annular flange formed on the clutch member F3.

Secured to the lower end of the arm 1-1 below the fulerum thereof is an arm H which extends rearwardly beyond the drag when in its lowered position and terminates in a foot piece zf, which is easily accessible to the operator.

.l designates a trip rod, the rear end of which is piv- Otally connected to the upper end of the arm H and 1 the forward end of which is loosely supported in an eye j secured to the inner side of one of the jack beams b b. The forward end of the trip rod I is threaded and has adjustably secured thereon on opposite sides of the eye j, for a purpose to be hereinafter more particularly set forth, nuts j and jg.

K designates a drag, which is of the Yusual construction and is pivoted in the usual manner to the lower end of a suitable conveyer L. The drive shaft K of the drag K is, as is usual in devices of this character, driven by a suitable chain from the drive shaft L of the elevator or conveyor L.

K2 designates a sprocket wheel, which is carried by a shaft journaled in a suitable bearing secured to the sides of the frame of the drag K and is provided with a laterally projecting sleeve c which is adapted to receive the projecting end of the shaft F, when the drag is in its lowered position, said sleeve being provided with a ratchet face adapted to eoperate with the ratchet face on the collar f secured to the projecting end of the shaft F. The sprocket wheel K2 is connected by a suitable chain with a sprocket wheel K3 se` cured to the drive shaft K of the drag K.

The beam 1 which extends rearwardly of the supporting beams A A to form a support for the drag K is provided with a stop t' having an inner beveled face which is adapted to contact with the rear edge of the drag when the same is lowered, thereby forcing the same inwardly and causing the sleeve l: ofthe sprocket wheel (30 K.2 carried thereby to engage the projecting end of the shaft F and the ratchet face of said sleeve to interlock with the ratchet face of the collar f secured to the projecting end of said shaft F. From this construetion it will be apparent that upon the lowering of the drag to its proper position, the power shaft L of the conveyor L will be automatically connected with the shaft Fr I will now describe the mechanism for raising and lowering the jack. The forward end of the shaft G has secured thereto a worm G3, which meshes with a worm wheel M keyed to a shaft M which is journaled in bearings m of any suitable construction secured t0 the forward ends of the supporting beam A A.

M2 designates a pinion, which is keyed to the shaft M at one side of the worm wheel M.

ilfeshing with the pinion M2 is a rack bar N, which is made up of a plurality of sections so thatthe same may be collapsed in the manner hereinafter set forth. The sections of the rack bar cach comprise a flat portion n having a plurality of teeth extending transversely thereacress and a rib 1t disposed in rear of said flat portion and medially thereof, one end of said rib projecting beyond the end of the fiat portion n and the opposite end of said rib being formed with a pair of separated ears a?, which also project beyond the end of the fiat portion n and are adapted to receive the projecting end of the rib n of the next adjacent section, which is pivoted therebetween by a suitable pivot bolt m3,

which passes therethrough. The adjacent ends of the flat portion n of the sections are provided with squared shoulders which abut when the fiat portions of the several sections are brought into alinement and form knuckle joints to prevent the rearward collapse of the rack bar, and as the rack bar N is rearwardly inclined, when the jack is in its elevated position it will be apparent that the weight of the wagon will hold the squared shoulders of the `flat portions n of the sections thereof in engagement and thereby prevent the collapse of the bar. The topmost section is provided with a laterally disposed sleeve formed integral therewith through which the pivot bolt d which. connects the links D D to the forward end of the jack passes.

O designates a frame in the ripper' and lower ends of which are journalcd rollers o, which contact with the rear face of the ribs n of the sections of the rack bar and hold the teeth thereof in engagement with the pinion M2. The frame O is carried by a shaft O, which is journaled in suitable bearings secured to the upper surface of the forward ends of the supporting beams A A, so that the same may accommodate itself to the change in the angle of the rack bar N caused by the elevation of the jack.

P designates an open frame, which is secured in any suitable manner to the forward ends of the supporting beams A A and is designed to constitute a housing for the collapsed sections of the rack bar N, said frame in the present embodiment of the invention being formed of a metallic strap which has its lower end secured in any suitable manner to the support-ing members A A directly below the pinion M2, the opposite end of said strap extending forwardly beyond the ends of the supporting beams and being bent upwardly and around and secured to the back of the frame O. -From the construction it will be apparent that when the rack bar is lowered, the sections thereof will Contact with the frame P and as they are free to collapse forwardly they will follow configuration of said frame and be stored in a convolute ferm.

l prefer to use in conjunction with the jack platform sections Q upon opposite sides thereof, the forward ends of which are provided with forwardly diverging centering rails Qf, similar' in construction to those illustrated in my application iiled Feb. 12, 1906, Serial No. SOILSZE). The platform sections are also provided with stop rails Q2 extending transversely thercacross which linrit the movement of the front wheels of the Wagon thereon.

Having descr'ibed the constr'rrction of my improved device l will now set for'th the operation thereof. The wagon is Iirst dr'ivcn into position onto the platform section Q so that the front axle thereof will be engaged by the forward end of the jack beams when the jack is elevated, the clutch member F3 is then moved to connect the pinion F with the shaft F', the drag I( is then lowered, which automatically connects the shaft F with the power shaft, thereby causing the rotation of the shalt G and consequently the elevation of the rack bar N. The upward movement of the jack continues until the eye j in one of the beams thereof contacts with the nut j carried by the trip bar and forces the same rearwardly a sullieient amount to disengage the clutch member F from the gear' wheel F which will stop the movement of the jack. To effect the lowering of the jack, the clutch member is moved into engagement with the sprocket wheel F2, which will obviorrsly cause the reversal of the direction of rotation of the shait G and consequently the lowering of thc rack bar and the jack. When the jack reaches its lowerinost position the eye j will contact with the nut j2 and rnove the trip .I a sufficient extent to disengage the clutch member F3 from the sprocket wheel F2. It will bc obvious that by adjusting the nuts j' and j on the trip bar' J that the movement of the jack may be limited as desired.
